[Resolved]  Reliance Communications — Termination of number

I have submitted a termination request form at "Prabha Communications Reliance World" in Karvenagar Pune, on 30th August' 08. The request was accepted, and my card was submitted. Also all my pending dues and termination amount of Rs.525 was also paid. I have a receipt for the same. I have left Pune and am currently based in Chennai.
Since that time I have been getting reminders for bill payment every month at my office address in pune, and now finally I have received a warning letter from Reliance for legal procedures. This is ridiculous !!! Its been 4 months and the records have not yet been updated that a no.has been terminated ?
when i called customer care, they told me that the no.is still active and is being used by someone and the dues have amounted to Rs.684 for which the bill is still being sent to me, although I am no more using Reliance.
I want to report the unauthorized usage of my card after Aug, 30th 2008 and want a confirmation that this issue has been closed, else I shall report this further on. This is not acceptable, as you cannot harass a customer, just because you guys are at fault somewhere!!!

Awaiting your response.
